Animal Agriculture and Antibiotic Resistance: Welfare and Public Health

Routine antibiotic use in livestock farming contributes to antimicrobial resistance, threatening both human health and representing a welfare concern driven by poor husbandry conditions.

Key Facts

An estimated 66% of global antibiotic use is in livestock, not humans
Antibiotics are often used prophylactically to prevent disease in crowded, stressful conditions
Antimicrobial resistant bacteria from farms can transfer to humans via food, environment, and direct contact
The WHO has listed antibiotic resistance as one of the top 10 global public health threats
Countries that have banned growth-promotion antibiotic use have not seen production declines
The EU banned routine prophylactic antibiotic use in livestock in 2022

Welfare Considerations

Antibiotic use in livestock is both a public health crisis and a welfare indicator. When antibiotics are needed routinely to keep animals alive in production conditions, those conditions are fundamentally inadequate for animal health. Improving housing, reducing stocking density, and eliminating stressors reduces disease and antibiotic need simultaneously - a case where better animal welfare directly supports better human health. Restricting antibiotic use without improving welfare simply produces sicker animals.

What You Can Do

Choose animal products from producers certified for low or no routine antibiotic use
Support policies restricting prophylactic antibiotic use in livestock
Reduce consumption of animal products from intensive systems
Advocate for linking antibiotic reduction targets to improved housing and welfare standards
